One problem with what our alleged TSA representative posting here observed about the limitations of profiling.

No, you can't tell by looking who is a terrorist. Yes, it could be a child or an old woman. So he thinks that means they are guilty until innocent and must be probed and groped until TSA is satisfied that they are not guilty (this time).

What he neglects to mention is that a terrorist could also pass a background check and wear a blue uniform and a shiny badge and work at an airport. But if the terrorist does that, from the day he gets hired, he will be above suspicion, innocent until proven guilty, and even then maybe not. No probing and groping, no accountability, no reliable record of his comings and goings and activities.

Because once he passes his little background check and gets that blue uniform and shiny badge, he's more American than any of the rest of us and he can't possibly be a terrorist.
